140 3.91 or 3.73 diff

I have one in Melbourne I think, but I never drove the 74 145 it came out of. Removed about 15 years ago. Hope to be over towards the end of the month and can take a look then.

I know that 140's did came with a 3.9:1 rear ratio, but have not heard of a 3.73:1 from factory fitted to a 140 series. Usually in 140's they are either 4.1:1 or 4.3:1, I suspect that the 3.9:1 ratio may have been fitted to those with an auto box.

If you are looking for a 3.73:1 final drive, best to get one from a 164. As far as I know, they should interchange readily.

Good luck with it.

Can you swap in a 87+ centre?

164 had 3.54 auto and 3.73 manual.

164 with a Holden motor on marketplace in Melbz going to parts or scrapped if not sold whole.
